某油气井场滑坡形成演化机制分析

文章通过详细的野外调查,基于地质过程机制分析法分析了滑坡的变形特征和失稳影响因素,提出了某油气井场滑坡的成因机制,将其形成演化过程分为原始坡体阶段、人类工程活动影响阶段和降雨影响最终失稳阶段,以供滑坡治理工程设计时参考,同时也警醒在此类区域进行工程建设时应充分考虑人类工程活动所带来的影响,为此类区域后续工程建设提供相应的参考。

through detailed field investigation, based on the analysis of geological process mechanism, this paper analyzes the deformation characteristics of landslide and the influencing factors of instability, and puts forward the genetic; mechanism of landslide in a certain oil and gas well site. The process of formation and evolution is divided into three stages： the original slope body stage, the human engineering activity influence stage and the rainfall influence final instability stage, which can be used as a reference for landslide control engineering design. At the same time, the influence of human engineering activities should be taken into full consideration when carrying out engineering construction in this kind of area, which can provide the corresponding reference for the subsequent engineering construction in this kind of area.
